If you watch the 56th Annual Grammy Awards on Sunday night, don’t expect to see too much hardware. Over the years, the telecast has been reducing the on-air trophy presentations in favor of “Grammy moments” — those often ill-fated collaborative performances between artists of different eras and styles.

In Sunday’s Washington Post, we argue that these manufactured duets are nothing more than icky brand synergy. They need to stop.

Below, some evidence of their pointlessness. Here are five recent Grammy moments that never should have happened.

1. Paul McCartney, Jay Z and Linkin Park in 2006

An already unseemly hip-hop-nu-metal-mash-up suddenly segues into …  a tender Beatles ballad. Why? Did anyone on earth — excluding the members of Linkin Park — enjoy this?

2. Chris Brown, David Guetta, Lil Wayne, Foo Fighters and Deadmau5 in 2012.

It’s still unclear what this was. A grab bag of artists helping Brown revive his reputation in the music biz? Egregious and grotesque.

3. Stevie Wonder and the Jonas Brothers in 2009.

Everything’s fine until Wonder rips into “Superstition” and the JoBros quickly prove how unworthy they are of this collaboration.

4. Kid Rock and Keely Smith in 2007.

A rap-rock dude and a storied jazz singer team up for one of the flimsiest Grammy duets of all time. Weird!

5. Taylor Swift and Stevie Nicks in 2010.

Swift won the trophy for album of the year later in the night, but this infamously off-key duet was the Grammy moment folks seem to remember her for.
